Salt Dough Maps and Now What?

When I was a kid in the sixth grade I had to make a salt dough map of South America.  When my oldest was in first grade we made one of our state, which was Washington.  Now my middle son is making one for his homestate of Colorado.  Since Colorado is essentially a rectangle, B got the easiest assignment of all of us.

I had him paint it to show elevations, label about 20 places, landforms and neighboring states and then create a key, scale and compass rose.  He answered a series of about 16 questions such as, "Which state does the Arkansas River flow into?" and, "What direction to the Rocky Mountains run?"

I think he enjoyed the project.

Now what do we do with it?
